FILTER.

Specification of Letters Patent.

Patented Aug. 8, 11916.

Application filed May 11, 1916. Serial No. 96,844.

To all whom it may concern:

Be it known that I, PHILIP J. BACHER, a citizen of theUnited States, anda resident of Galesburg, in the county of Knox and State of Illinois,have invented a new and useful Filter, of which the following is aspecification.

My i vention relates to filtering means and par cularly to that type orclass thereof used for filtering and separating the water and sedim tfrom oils, such as gasolene.

As the nature of the invention is more fully disclosed it will beevident that my improvements may be used for various fil- 'termgoperations, such as removing the saponaceous matter from the gasoleneused in cleaning establishments, etc.

The primary object of the invention is to simplify and improve theconstruction and increase the efficiency of devices or apparatus of thisnature. Y

In the accompanying drawings, which illustrate a preferred embodiment ofmy invention, Figure 1 is a sectional 'view, partly in elevation; Fig.2, a plan of either of the upper screens, inverted; and Fig. 3, anelevation of either of the upper screens.

Considering the drawings in detail, 2 indicates a frame on which rests asupply tank 3.

' 4 indicates a bracket secured to the frame 2.

5 designates a filter-tank.

(3 denotes a connecting or supply pipe.

7 designates a conical bottom the upper edge of which is secured in thebottom of the tank 5 by soldering or otherwise.

8 indicates a ring having a flange 9, these forming a cup 10. The loweredge of the tank 5 rests on the flange S) and the bottom 7 seats in theopening 11 provided by the ring 8.

12 designates a frame in which is mounted a telltale or indicating glass13 which coinmunicates by means of couplings 14 with the bottom 7.

15 denotes a receiving cup, preferably of glass and fitted at its topand bottom with caps'lti, 17, the former threaded onto a ipple 18 andthe latter colmnunicatmg with a pet-cock 19. One branch of a T-connector20 engages the nipple 18, a second branch engages a nipple 21 whichcommunicates also with the tell-tale 13, and the third branchcommunicates with a discharge pipe carrying a pct-cock 23andglobc valve23'.

24 indicates theoverflow pipe, and 25 indicates a cover or top having ahandle 26.

round the hoop 30, whereupon they are stitched through the meshes of thescreen 31 as shown at 35 to their own body portions; A. ring 33 isstitched into or otherwise engaged with the apex of each unit 27, 28 and29, and the two last recited ones are provided each with legs 34,preferably Secured to the wire-screen 31.

36 designates mixed water, gasolene, soap or the like, and dirt. 37indicates this mixture after a part of the water, soap and dirt havebeen removed by the filter; 38 indicates it after it has passed throughthe filter 28, whereby most of the heavier portions have been removed,and 39 indicates the substantially pureegasolene after it has passedthrough the filter 27.

In operation, the'pressure of the mixture 36 in the supply tank will beforced through the lower wire-screen 31, which will obstruct andprobably prevent the passage of all the particles of dirt. A portion ofthe mixture will pass on through the absorbent separating material 32,which will become saturated with water but which will retain but aminute quantity of gasolene. This screen 32 removes also practically allof the saponaceous matter. Some of the water which is forced through theprimary screen 32 will adhere thereto and run down its taupper screen itwill be practically pure gasolene, whatever water comes in contact, withthe absorbent member thereof falling down onto the one next below, andso on, eachv becoming saturated and the surplus dripping off. The wastewater 41 and heavy sediment 42 will pass into the receiver l5 and may bedrained of? by the pct-cock 19.

Or the receiver 15 may bc-unscrcwcd from filtering units at properdistances of separation. When it is desired to remove said units, forcleansing or for any other purpose, this may be readily done by means ofthe rings 33. The ring 10 supports the tank firmly'and securely, forminga support for both its lower edge and for the conical bottom, andpermits ready removal when for any purpose it is desired that it beremoved.

Having thus described my invention I claim as new the following, to-wit:

1. A filter-unit comprising a hoop, a conical Wire-mesh strainer fittedat its base thereto, legs soldered to said strainer, and a conicalabsorbent filtering-element fitted to said strainer, the edge portion ofits base folded over said hoop and stitched to its own body portion andthrough said mesh.

2. In a filter, a filter-tank, means for funishing liquid thereto, anoutlet pipe for the sediment, an outlet pipe for the purified i; liquid,and a filtering unit removable from.

the tankand comprising a hoop, a conical Wire-mesh strainer fitted atits base thereto,

and a conical absorbent filtering element fitted to said strainer, theedge portion of its base folded over the hoop and stitched to its ownbody portion and through said mesh, and said folded edgeresting in closecontact With the inner Wall of the tank.

3. A filter-unit comprising a hoop, a conical Wire-mesh strainer fittedat its base thereto, and aconical absorbent filtering element fitted tosaid strainer, the edge portion of its base folded over saidhoop andstitched to its oWnbody portion and through said mesh.

In Witness whereof I hereunto subscrib my name this 6th day of May,1916.

PHILIP J. BACHEH.
